My Daughter Had A CD57 Test. The Results Are 70.

My daughter had a CD57 test. the results are 70. She took the test because I believe she had a rash that I didnt realize until several months later may have been a lymne tick rash. She seems to have no symptoms and is feeling healthy but it is strange the the test came back so low. Her doctor said that their clinic diagnosis lymne if you are in the range of 40 or less. However my research on the web says 60 or less and maybe even 60-100. Her doctor is suggesting that she may be fighting an infection either bacterial or viral and wants her to get a stool sample for a thorough test. Not sure how to move forward.
